One was the closure of our collaborative middle school educational programmes by the Madhya Pradesh government in July 2002 The second was the bifurcation of Eklavya into two autonomous units - a 'school education and publication' group and a'rural development'group.The latter was registered as a new society on August 1 1, 2003 as the Samavesh Society for Development and Governance. -
16 February 2016 Prof. M. Jagadesh Kumar Vice Chancellor
16 February 2016 Prof. M. Jagadesh Kumar Vice Chancellor Jawaharlal Nehru University New Delhi-110 067, India Dear Prof. Kumar, We are writing, as a group of academics, to express our deep disappointment with your actions in the event leading up to the arrest of several students last week. We understand that last Tuesday, a student group organized a rally to commemorate the death anniversary of Afzal Guru. The police alleges that some of the students voiced controversial opinions. The police then proceeded to arrest the president of the JNU Students Union, Kanhaiya Kumar, and charged him with sedition. This has been followed by a number of further arrests. What is most disturbing is that the JNU administration appears to have defended and aided these repressive actions by the police, rather than defending the students who were involved in a non-violent activity. The arrest of the president of the JNUSU is especially troublesome since he was not even an organizer of the rally but merely present to express his solidarity. However, even as far the organizers and the speakers at the event are concerned, we hope that you recognize that expressing controversial views in a peaceful forum cannot be equated with sedition. For example, many people believe that Afzal Guru was let down by a lack of appropriate legal representation in his trial, and that his execution was therefore a grave miscarriage of justice. One may agree or disagree with this viewpoint — and, indeed, signatories to this letter hold different positions — but we are unanimous that students should have the right to freely discuss this issue. -
